The problem
From time to time, I have the following problem in JDeveloper after I create a new Application with a template including JSF:I cannot see the palettes ADF Faces Core and ADF Faces Html from the drop-down list in the Component Palette:
and when I drag and drop an element from the Data Control palette in a new JSF JSP page, the tags are not executed in the Visual Editor:
If you look at the Structure window, you can see a warning No grammar available for namespace http://xmlns.oracle.com/adf/faces/html, contents of element html cannot be validated:
The cause
I suspect this happens after JDeveloper was inactive for a while.I logged Bug 5232205 (requires an access to MetaLink) to report this issue.
The solution
Just close and restart JDeveloper. You will see ADF Faces Core and ADF Faces Html in the Component Palette:
and the tags will be executed in the Visual Editor:
